Bun crashes when reading very large file via Bun global #15242

Closed Daw588 closed 1 day ago

Daw588 commented 3 days ago

How can we reproduce the crash?

Get a very large file like 5GB video file and try to load it into the memory via Bun global:

await Bun.file("./very-large-file").arrayBuffer();

Note: This doesn't happen with NodeJS API readFile, as an error "out of memory" is thrown.

Relevant log output

panic(main thread): Internal assertion failure

Stack Trace (bun.report)
